        distrib/utils/sysinst/mbr.c: revision 1.91
Fix regression by my dumb patch in PR/45990.
sysinst fails with "floating exception" after
changing MBR partition size in MBR editor menu
if the target disk doesn't have valid MBR partition
or has a valid partition 0 whose offset is not 1MB aligned
(like 63 sectors).
read_mbr() (which calls get_ptn_alignment()) is called
before set_bios_geom(), so bhead is not initialized there
and ptn_alignment could be zero.
To workaround, explicitly call get_ptn_alignment() again
in edit_mbr() to update ptn_alignemnt per BIOS geom values.
